BACKGROUND Optical vortices provide one of the promising solutions for enhancing the
capacity of data multiplexing to meet an unprecedented growth in big data and internet traffic …

Structured light with inhomogeneous phase, amplitude, and polarization spatial distributions
that represent an infinite-dimensional space of eigenstates for light as the ideal carrier can …

Toroidal vortices, also known as vortex rings, are whirling, closed-loop disturbances that
form a characteristic ring shape in liquids and gases and propagate in a direction that is …

A survey of some recent theoretical and experimental studies on localized structures that
form and propagate in a broad class of optical and matter-wave media is presented. The …

Today, it is well known that light possesses a linear momentum that is along the propagation
direction. Besides, scientists also discovered that light can possess an angular momentum …

Structured light recently highlighted the higher-dimensional control with many tailored
degrees of freedom (DoFs) such as amplitude, wavelength, polarization, and orbital angular …

Spatiotemporal vortices of light, featuring transverse orbital angular momentum (OAM) and
energy circulation in the spatiotemporal domain, have received increasing attention recently …

Space-time wave packets (STWPs) constitute a broad class of pulsed optical fields that are
rigidly transported in linear media without diffraction or dispersion, and are therefore …

Spatiotemporal sculpturing of light pulse with ultimately sophisticated structures represents a
major goal of the everlasting pursue of ultra-fast information transmission and processing as …

Recently, spatiotemporal optical vortex pulses carrying a purely transverse intrinsic orbital
angular momentum were generated experimentally [Optica 6, 1547 (2019) OPTIC8 2334 …
